CARSON: Flavia Pennetta of Italy, last year's runner-up and the No. 10 seed, beat Varvara Lepchenko of the United States, 6-2, 5-7, 6-0 at the L.A. Women's Tennis Championships on Monday, while top-ranked Dinara Safina and the other top seeds had the day off.

Safina, responded Monday to comments made by Wimbledon champion Serena Williams and others about her qualifications to be the top-ranked player on the WTA Tour.

"Ranking is ranking. I didn't do the ranking system," said Safina, the defending champion at Carson, California.

It wasn't a good day for the other seeded players as Anna Chakvetadze of Russia beat No. 11 Virginie Razzano of France, 7-6 (5), 6-3, Lucie Safarova of the Czech Republic ousted No. 15 Kaia Kanepi of Estonia, 6-3, 7-6 (4) and U.S. qualifier Jill Craybas upset No. 16 Francesca Schiavone of Italy, 7-6 (7), 6-2.

Maria Sharapova continued her comeback from injury by beating Australian Jarmila Groth 6-0, 6-4, and CoCo Vandeweghe of the United States beat Italy's Tathiana Garbin 6-4, 6-4 in the late matches.

Safina spent her day off answering questions pleasantly.

"If she (Williams) has some questions she can give those questions to the WTA, who is doing the ranking system," Safina said. "It's just the result of how you play the whole year,not just the four Grand Slams. I've been playing the whole year and I've been having great results all through the Grand Slams. If she has some questions she can go to the WTA." Safina, 21, was No. 9 in the rankings when she won this event a year ago. She won two more tournaments, was the silver medalist in the Olympics and a semifinalist at the U.S. Open (where she lost to Williams) and compiled a 22-7 record that included losses to Venus and Serena Williams and Elena Dementieva in the Tour Championships.

She started this year No. 3, ascended to No. 1 on April 20 and has a 47-9 record that includes three titles, four finals and two semifinals. But she lost to Serena, 6-0, 6-3, in the Australian Open final and to Venus, 6-0, 6-1, in the Wimbledon semifinals.

Serena had said before Wimbledon that everyone knew who the real No. 1 was. After winning her third Grand Slam in the past year she wondered aloud how she could not be No. 1 on the WTA computer and said, sarcastically, that "Dinara did a great job to get to No. 1, she won Rome and Madrid." Safina said she doesn't feel any urgency to win a Grand Slam, that "it's just a matter of time and one day it will happen." When told that Jelena Jankovic said last week that to be No. 1 "you have to be beating the Williams sisters," Safina smiled and shrugged and said, again, "the ranking system is not only if you beat Serena Williams and Venus Williams. It's based on how you play the whole year, and what is their record."
